All Flashcards
What happens to the electric potential (V) as the distance (r) from a point charge approaches infinity?
V approaches 0.
What is the effect of doing work by an electric field on potential energy?
It decreases the potential energy.
What happens when a charge moves along an equipotential line?
No work is done.
What happens to kinetic energy when it is converted to potential energy?
Kinetic energy decreases and potential energy increases, conserving total energy.
How do you calculate the total electric potential energy () for multiple charges?
Sum all individual values, considering positive and negative signs.
How do you calculate the electric potential due to multiple charges?
Sum the individual electric potentials contributed by each charge.
Describe the process of finding the change in voltage () using an integral.
. Integrate the negative dot product of the electric field and displacement from point a to point b.
For a point charge, what is the shape of equipotential lines?
Concentric circles centered on the charge.
What is the relationship between electric field lines and equipotential lines?
Electric field lines are always perpendicular to equipotential lines.
